Yes, a 3D-printed 2D thing. BUT – that means that just about any image can be extruded and given depth!
I got a request for a Turkey pie-topper and accepted the challenge with an Instructable. Tinkercad has a couple of options to do this – SVG Import and Image Generator. For this decorative stake, I knew I wanted a silhouette, rather than a photo-type image, so here’s a walkthrough to make one using the SVG Import feature. Also, here’s a link to the model itself if you want to crack it apart.
